Abstract:
Objective To evaluate the application of intraoperative real-time ultrasound combined with neuronavigation in surgical resection of deep intracranial lesions. Methods Fifteen patients with deep intracranial lesions underwent surgical resection of the lesions with guidance by Brain-Lab neuronavigation and intraoperative real-time ultrasound. The lesions were localized by ultrasound, and in cases of brain shift, intraoperative real-time ultrasound was used for lesion relocalization, surgical guidance, and monitoring of the tumor remnants during the operation. Results The lesions and their surrounding structures were accurately localized. Intraoperative real-time ultrasound identified brain shift of varying degrees, which was corrected under ultrasound guidance. Total resection of the lesions was achieved in 12 cases, and subtotal resection was performed in 2 cases. In the other case, the inflammatory lesion was identified as chronic granuloma by biopsy. All the patients showed improvements of the clinical symptoms after the operations. Conclusion Intraoperative real-time ultrasound during neuronavigation allows accurate localization of deep intracranial lesions and facilitates preoperative surgical planning to define the scope of resection, avoid the cortical brain tissue and important deep structures, and help evaluate the lesion residues for a second operation. Intraoperative real-time ultrasound may help improve the therapeutic effects and reduce the surgical complications.
